Three-dimensional simulations of the jet feedback mechanism in common envelope jets supernovae

ABSTRACT We conduct three-dimensional hydrodynamical simulations of common envelope jets supernova (CEJSN) events where we assume that a neutron star (NS) launches as it orbits inside the outer zones red supergiant (RSG) envelope, and find negative jet feedback coefficient to be ≃ 0.1–0.2. This is factor by which reduce mass accretion rate on NS they remove from inflate bubbles (cocoons). Our results suggest in most CEJSN NS-RSG binary system experiences grazing evolution before enters full (CEE). also induce upward downward flows RSG envelope. These together with strong convection stars might imply energy transport CEJSNe very important. Because limited numerical resources do not include gravity NS, nor process, launching deformed Future CEE NS/BH companion should process (and vary jets’ power accordingly), gravitational interaction RSG, convection.
